Picheo is a popular slang word from the Caribbean, especially Puerto Rico, that means 'to ignore' or 'brush someone off'. It's a fantastic example of Spanglish, as it comes from the English word 'pitcher' from baseball!
In the song, Omar Courtz sings, 'Yo a veces picheo' (Sometimes I ignore you), describing a situation where he's playing it cool and pretending not to be interested. It's a fun, memorable word that captures a very specific feeling of dodging or ignoring someone, just like a batter dodges a pitch.
Puerto Rican artist Omar Courtz sets up a late-night bedroom hookup that relies on a classic excuse: putting on a movie nobody plans on watching. The title track detail is great, too—she always plugs in the colorful mood lights ("Luces de colores siempre las enchufa") right before taking off her top so he finds his creative spark ("Se quita la blusa, eso lo hace pa' que coja musa"). Between rolling weed and hooking up, he boasts that his scent lingers on her skin even after she takes a shower, which keeps her texting him to come back over.
The real friction comes from heavy Puerto Rican slang about caught feelings. She tells him "Vuelve" ("Come back"), but he admits, "Yo a veces picheo, mami, porque te me envuelves" ("Sometimes I ignore you, girl, because you get too emotionally attached"). In local street talk, pichear means to ghost, ignore, or brush someone off, while envolverse means catching feelings and taking a casual fling way too seriously. He wants the easy routine—smoking, passing the night together, and hooking up "poco a poco" (little by little)—without having to deal with the messy romantic strings that come when someone falls in love.
